This doesn't relate directly to owning an EV but I just found out while researching rates that people using CPAP machines for obstructive sleep apnea (snoring) qualify for an additional 500kWh of power at their baseline rate. For someone like me, who always finishes a month in Tier 4 or 5, this can be a huge savings. There is information and a form for your doctor to fill out available at: http://www.pge.com/en/myhome/customerservice/financialassistance/medicalbaseline/index.page
